SK-2708: Fix README and sample gaps

Summary

• Documented all previously undocumented or under-documented public exports in README.md
• Fixed incorrect and deprecated API usage across sample files
• Expanded all Options classes in samples to show every available setter as commented alternatives, following the file-upload.ts pattern

---

README changes

New sections added

• Runtime client management — documents all 12 Skyflow class public methods (addVaultConfig, updateVaultConfig, getVaultConfig, removeVaultConfig, addConnectionConfig, updateConnectionConfig, getConnectionConfig, removeConnectionConfig, setLogLevel, getLogLevel, updateSkyflowCredentials, getSkyflowCredentials) with code examples
• Configure a connection — documents ConnectionConfig shape (connectionId, connectionUrl, optional credentials)
• Per-record errors (SkyflowRecordError) — documents the error shape returned in response.errors arrays
• TypeScript types reference — new section covering credential sub-types, response record interfaces, request item shapes, and FileInput

Existing sections expanded

• InsertOptions — added setTokens, setHomogeneous, setTokenMode + full TokenMode enum table
• UpdateOptions — added code example using UpdateOptions + reference table for all 3 setters
• GetOptions — added reference table for all 9 setters + OrderByEnum table
• FileUploadOptions — added reference table for all 5 setters (setFilePath, setBase64, setFileName, setFileObject, setSkyflowId)
• DeidentifyFileOptions — added reference table for all 15 setters including image, audio, PDF, and Bleep class setters
• TokenFormat — added setVaultToken, setEntityUniqueCounter, setEntityOnly alongside existing setDefault
• generateBearerToken / generateBearerTokenFromCreds — documented BearerTokenOptions and GenerateTokenOptions types
• generateSignedDataTokens — merged generateSignedDataTokensFromCreds into same section with SignedDataTokensOptions type
• VaultConfig — added optional credentials field
• isExpired — added usage example

Bug fixes

• Removed DELETE from RequestMethod values list (not in the enum)
• Fixed optionsText typo → options in De-identify Text example
• Fixed undefined variable references in Runtime management code blocks (updatedCredentials, updatedConnectionConfig, newCredentials)
• Fixed creds undefined variable in credential sub-types example
• Fixed http_code → httpCode in error handling example (camelCase is the current API)

---

Sample changes

samples/README.md

• Added 5 missing files: client-operations.ts, credentials-options.ts, data-residency.ts, deidentify-file-with-filepath.ts, deidentify-file-with-filepath-async.ts
• Corrected insert-byot.ts label from "Upsert operations" → "Insert with bring-your-own tokens (BYOT)"

Misleading placeholder values fixed

Replaced skyflow_id-prefixed placeholder strings that looked like the deprecated skyflow_id API field:

File	Change
insert-byot.ts	Data values 'skyflow_id1'/'skyflow_id2' → '<TOKEN_1>'/'<TOKEN_2>'; token: 'bearer' → '<BEARER_TOKEN>'
detokenzie-records.ts	token: 'token' → '<BEARER_TOKEN>'
delete-records.ts	Record IDs 'skyflow_id1–3' → '<SKYFLOW_ID_1–3>'
credentials-options.ts	Record IDs 'skyflow_id1–6' → '<SKYFLOW_ID_1–6>'

Internal ticket references removed

• update-record.ts — removed // SK-2812: comment
• get-records.ts — removed // NEW API (SK-2812): comment and deprecated setDownloadURL reference

Deprecated field reference fixed

• deidentify-file-with-filepath-async.ts — error.error?.http_code → error.error?.httpCode

Missing options added (as commented alternatives)

File	Options added
file-upload.ts	setBase64 + setFileName (Option B), setFileObject (Option C)
insert-records.ts	setContinueOnError, setUpsertColumn, setHomogeneous
update-record.ts	setTokens, setTokenMode
get-records.ts	setRedactionType, setFields, setOffset, setLimit, setOrderBy, setDownloadUrl, setColumnName/setColumnValues
get-column-values.ts	setRedactionType, setFields, setOffset, setLimit, setOrderBy
deidentify-text.ts	setVaultToken, setEntityUniqueCounter, setEntityOnly on TokenFormat; fixed optionsText → options

Test plan

• Verify all README code examples compile without TypeScript errors
• Verify all sample files run successfully against a real vault
• Confirm no deprecated field names (http_code, skyflow_id, request_ID) remain in active sample code
• Confirm all samples/README.md links resolve to existing files
