… validation failures

…heck

Modified the pre-commit hook to pass only staged markdown files to
markdownlint instead of running it on all files in the project.

Changes:
- Extract staged markdown files excluding docs/sdk/
- Pass filtered list directly to markdownlint via xargs
- Consistent with Prettier formatting approach (staged files only)

This ensures developers aren't blocked by markdown issues in files
they're not modifying, while still validating all committed changes.

…warning

TypeScript's tsc command requires full project context for accurate type
checking and cannot be limited to only staged files. This change:

- Adds SKIP_TS_CHECK environment variable to bypass the check
- Warns users that TypeScript checks the entire project
- Provides clear instructions when check fails on unrelated errors
- Improves error messages to explain the project-wide scope

Usage:
- One-time skip: SKIP_TS_CHECK=1 git commit
- Permanent skip: export SKIP_TS_CHECK=1 (add to shell profile)

This prevents blocking commits due to unrelated TypeScript errors while
still allowing teams to enforce TypeScript checking when desired.

This reverts commit 9ca0617.

Vercel uses path-to-regexp v6.1.0 which requires specific syntax:
- The ? modifier only applies to parameters (like :param?), not literals
- Using /? at the end of paths is invalid syntax
- Vercel handles trailing slashes automatically with strict: false

Changes:
- Removed /? suffix from all 423 redirect source patterns
- Pattern /anytrust/? → /anytrust (now matches both /anytrust and /anytrust/)
- Follows path-to-regexp v6.1.0 syntax requirements

This fixes the error:
"Redirect at index 1 has invalid source pattern /anytrust/?"

Refs: https://vercel.com/docs/errors/error-list#invalid-route-source-pattern

Fixed 4 additional patterns that had ? suffix without /:
- /sdk-docs/dataEntities/networks? → /sdk-docs/dataEntities/networks
- /sdk/introduction? → /sdk/introduction
- /sdk/utils_multicall? → /sdk/utils_multicall
- /stylus/tools/stylus-cli? → /stylus/tools/stylus-cli

These patterns were also invalid in path-to-regexp v6.1.0 syntax.
Vercel dev now starts without any pattern validation errors.

Added "trailingSlash": false to vercel.json to ensure all URLs with
trailing slashes are automatically redirected to their non-trailing-slash
equivalents. This provides consistent behavior across all 2,000+ redirects
without needing individual /? suffixes on each redirect pattern.
